CARBURETER.

SPECIFICATION formingpart of Letters Patent No. 670,433, dated March 26, 1901.

Application filed July 9, 1900. Serial No. 22,948. (No model.)

To all whom it may concern:

Be it known that I, WALTER J. POWERS, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Gasolene-Gas Machines, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to devices for manufacturing gasolene-gas; and its object is to provide the same with certain new and useful features hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 is a transverse vertical section of a device embodying my invention. Fig. 2 is a section of the same on the line'2 2 of Fig. l, and Fig. 3 is a detail showing one of the pressure reducers or regulators in side elevation and a portion of the carbureting-chamher in section.

, Like letters refer to like parts in all of the figures.

A is an airtight cylindrical tank, and B is a diaphragm dividing the interior space into a large upper chamber and a smaller lower chamber. Within the lower chamber and depending from the diaphragm is a convoluted wall extending downward into the carbureting-chamber to near the bottom thereof, said chamber being adapted to be partially filled with gasolene from a suitable stand-pipe or tank D, which is connected to said chamber near its bottom by the pipe E.

To automatically maintain the gasolene in the carbureting-chamber at a given height, a small pipe F extends downward within the stand-pipe D from near its top, thence through its side near the bottom, and is connected to said carbu'reting-chamber .at a height above the bottom thereof at which it is desired that the liquid-level shall be maintained. The upper open end of said pipe F is protected by a shield F, and the upper end of the standpipe D is closed and made air-tight bya screwplug D, which may be removed for the purpose of refilling the stand-pipe.

To indicate the height of the gasolene in the carbureting-chamber, a gage-glass G is provided.

H is any suitable hydraulic air-pump provided with the usual water-inlet H and outlet H the inlet-pipe being provided with the usual pressure-regulator H H is the air-inlet for the pump, and I the outlet-pipe which conveys the compressed air to the upper chamber of the tank A. Said pipe I is provided with a shut-0E valve I and also a pressure-gage J. An outlet-pipe K is attached to the side of said air-chamber and, extending'upward and over the same, is connected to a pipe L, located within the axis of the tank A, and, extending downward through the diaphragm B, opens into the eye of the passage formed by the convolute wall 0. An outlet-pipe M to draw off the gas from the carbureting-chamber is connected to the side of the tank at the opposite or outer end of said passage, and in this pipe is interposed a suitable pressure reducer or regulator N. between said tank and the service-pipe O, which leads to any desirable point.

The air-pump is operated by Water-pressure from the city waterworks and automatically maintains a pressure of twenty-five pounds, more or less, to the square inch in the airchamber,which serves as a storage-tank, from which the air is drawn off through the pipe K and pressure-reducer K, which reduces the pressure to about three pounds. The air under this lightpressure is supplied to the carburetiug-chamber. in auniform flow, no matter how irregular the consumption of gas may be, and is freed-to flow slowly over the surface of the gasolene around the many turns of this convolute passage. The result is its thorough'carbureting, while at the same time the gasolene is not robbed of its lighter con- 'stituents, leaving a worthless residue, as is the case when it is held in the meshes of a fabric and exposed to the air. By consumption'the; gas is drawn off from the outer end of this passage through the pipe M and pres sure reducer or regulator N, which still further reduces the pressure to about two-tenths of a pound. The gas is thus supplied to the service-pipe O at a very low pressure and a regular flow maintained, which is very necessary to secure the best results.

The stand-pipe D being air-tight, gasolene will not flow therefrom through the connecting-pipe E unless air be admitted. Therefore when the gasolene in the carburetingchamber is above the lower end of the pipe F no air can get into the stand-pipe and no gasolene will flow therefrom; but as soon as the level of the gasolene in said chamber falls below the end of said pipe F air will flow up the same into the upper part of the standpipe and gasolene will flow through the pipe E into the carbureting-chamber until the gasolene-level is again raised and the flow of air out off.

My improved gas-machine being of very simple construction and wholly automatic in its operation is specially adapted for a domestic plant in which these features are of most importance.

What I claim as my invention is 1. An automatic gas apparatus, comprising a tank divided by a diaphragm into an upper compartment forming a permanent reservoir for the storage of compressed air and a lower compartment provided with means for carbureting air, a liquid-hydrocarbon-supply tank connected to said lower compartment and adapted to automatically supply the same with liquid from said tank, a hydraulic aircompressor connected to the upper compartment for automatically supplying the same with compressed air and maintain the same therein at a fixed maximum pressure largely exceeding the service-pressure of the gas, a compressed-airsupply pipe from the upper compartment into the lower compartment, a differential fluid pressure regulator in said pipe adapted to control the flow of compressed air in said pipe and maintain the same at a fixed pressure in the lower compartment higher than that of the service-pressure but lower than that in the upper compartment, a gas-supply pipe from the lower compartment to the burners and a differential fluid-pressure regulator in said pipe adapted to control the flow of gas from the lower compartment into said supply-pipe and maintain the same therein at the service-pressure required for the proper consumption of the gas.

2. An automatic gas apparatus, comprising a cylindrical tank, a diaphragm horizontally dividing the same into an upper compartment forming a permanent reservoir for the storage of compressed air and a lower compartment containing a supply of liquid hydrocarbon, a liquid hydrocarbon tank connected to said lower compartment and adapted to automatically maintain therein the supply of hydrocarbon, a hydraulic air-compressor connected to said upper compartment and adapted to automatically maintain the air therein at the limit of the compression due to the automatic operation of said compressor, a pressure-regulator in the water-supply pipe of said air-compressor as a means for regulating the maximum compression of air in said tank, a compressed-air pipe leading from the upper compartment exteriorly thereof into the lower compartment a diiferential fluid pressureregulating device in said pipe adapted to antomatically control the flow of com pressed air into the lower compartment and maintain the same therein at a pressure below that in the upper tank and above that required for the economical consumption of the gas at the burners, and a diiferential fluid-pressure regulator in the gas-supply pipe from the lower compartment to the burners adapted to control the supply of gas from the lower compartment into the gas-supply pipe and reduce its pressure to that required for the economical consumption of the gas at the burners.

In testimony whereof I affix my signature in presence of two witnesses.
